info Chevy P30 hydro boost brake/power sterring bleeding

I've never bled the hydro boost system on any chevy when replacing the lines. Simply steer to both sides and that's it. The brakes I just have someone pump the pedal several times, hold it, then I crack a bleeder open, and close it just before the fluid stops. And repeat as needed. I always start at the rear, it takes a while before you see bubbles at the rear, since the line is so darn long. I've tried using vacuum and pressure breeders but they just don't work as well as the pedal method for me.
